Pingdom is probably one of the more well-known website speed test tools. Their reports are divided into four different sections which include a waterfall breakdown, performance grade, page analysis, and history.
The page analysis offers a great overview with additional information such as a size analysis, size per domain (you can easily compare your CDN assets size vs your domain), the number of requests per domain, and what type of content had the most requests.
Pingdom's speed test tool also allows you to test your website's speed from more than 70 different locations.
The results of a Pingdom speed test provide you with performance insights, similar to Google PagesSpeed Insights, which outline where you can make improvements. The results also break down the page size by content type, page size by domain, requests by content type, and requests by domain.
